GASKET FOR T-ALCUM POWDER CANS Filed May 11, 1928 INVENTOR BYaJMKW ATTORNEY Patented Ma 2 193-1 UNITED STATES PATENT ounce EDMUND HOFFMAN, OF BROOKLYN, NEW YORK, ASSIGNOR TO AMERICAN CAN COH- IANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY I GASKET FOR TALC'UM POWDER CANS Application filed May 11, 192s.*seria1 1105276338.

This invention relates to metallic containers but more particularl to containers having sifter tops andwhlch are designed to contain such light, fine powders as talcum powder and the like.

Considerable trouble. has always been experienced with containers of this type, due to the fact that when they are filled with a fine powder, such'asfine talcum powder, the

10 powder leaks out around the edges of the but a very few shapes, such as round, oval or.

oblong; and even with the oblong containers the straight lines on the 'body required a heavy reinforcement so that the sides and ends would not collapse when the tight fitting covers were applied.

llt is the principal object of this invention to provide a container for such powders which will overcome thisundesirable leaka e.

it further object is the provision of such a container which can be made and furnished to the trade in a more numerous assortment of shapes substantiall ,as economically as the type formerly use a it further object of this invention is to provide a container which does not require the exact precision in manufacture as was formerly necessary.

A novel feature of my invention is the means of making the container leakproot. L Another novel feature is in the way in which the learoot feature is introduced and engaged by the container to reap the bene- Numerous other objects and advantages of understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

' Eigure 1 is a view of a container with parts broken away to show-the assembly;

Fig. 2 is a plan View of a washer used between the cover and the body of the container, and g I V Fig. 3 is an enlarged detail showing the assembly at the j washer and side walls.

uncture of the top piece, the

. A can 11 of sheet metal of the usual type is provided but at the top edges of the container the inturned peripheral lip 16 is formed. A. top member v12 is provided as usual to frictionally engage thebody member. The top member is or may be constructed with a shoulder along its outer periphery and the usual flange 21 extendin downwardly therefrom. An open type sii ter top 13 is firmly secured to this top member. To secure a powder-tight seal closure, 1 provide a washer 15, having a central aperture 19,

which is designed to be interposed between the body member and the top member, the washer 15 having suficient size to slightly extend beyond the inturned lip formed on the body. This washer may be made of such material as blotting paper or other similar material, which is soft enough to be readily engaged by the inturned lip 16 along the top of the body member. ll also provide another washer 17 of the same nature to be interposed between the sifted top '13 and its ca 18..

hen the container'is assembled as shown in Figure l, the washer engages between the inturned lip 16 of the body member and the shoulder it of the top member, the flange 21 of the top member extending downwardly over and frictionally engagin the side walls of the body member. When t e top member is put in place, the portionot the washer 15 extending outwardly beyond the inturned lip 16 of the body member is forced into the groove between the inturned ii and the flange of the top member efiectua y sealing the contents into the interior and preventing leakage between the two. This is especially effective at the side seam of the bodymlemher, which is the most difi cult portion of the container to. seal. The necessity for the absolute tight closure between the flange of the top and the side wall of the body formerly necessary is obviated, since the washer actually acts along the shoulder in the top 7 member. The washer 17 between the sifter top and the cap efi'ectually seals the space between these two and prevents leakage at this point.

It is thought that this invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that many changes may be made in the form, construction and arrangement of the dparts without departing from the spirit an scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim: T

1. In a container forli ht fine powders a body member open at t e top, a washer of sheet material across the top end of the body member into which the presented top end is indented, and-having a hole through which material in the body is discharged from the body, said washer having a wide stifi body portion, and a to closure member having an external flange riven and tightly fitting'down over the'end of the body and permanently pressing the washer thereagainst.

2.1m a container for light fine powders, a body member havin its edges interposed in a side seam, a was er of sheet material having a wide stiif body portion and arranged above the end of the can body and;

indented by the edge of the body and abutting on and closing the end of the side seam and having a hole through which material in the body is discharged from the body and a top closure member having an internal flange driven andtightly fitting down over the end of the body and permanentlypressin the washer thereagainst to close said contamer against leaking at the end of the side seam.
